Downgrade ipywidgets to version 7.7.2

[ArthurAsenheimer]

Expected Behavior

The library ipywidgets is supported.

Actual Behavior

QuantConnect uses the release candidate 8.0.0rc1 which doesn't work well in VSCode's Jupyter Notebook environment.
IPyWidgets 8 is not officially supported by VSCode as you can see here.
There are a lot of issues with version 8 of ipywidgets as you can see here and here.

Potential Solution / Workaround

Uninstall ipywidgets 8 and install ipywidgets==7.7.2 instead.

Hey @Martin-Molinero ,
it probably doesn't make sense to downgrade to an older version. The responsible team has already started working on it (PR). And according to this comment, support for IPyWidgets 8 is planned for the February release. I think it's best to give it a few more weeks before taking any action.
